Khi việc sử dụng các nguồn năng lượng thay thế tăng lên, việc tiêu thụ nhiên liệu hóa thạch của Trái đất cũng sẽ giảm xuống. Một watt năng lượng được sử dụng bởi pin mặt trời bằng một watt ít hơn được sử dụng bởi các nhà máy điện đốt dầu hoặc than. Nếu xã hội hy vọng thấy thế hệ tiếp theo có các nguồn lực cần thiết để sưởi ấm nhà cửa và lái xe ô tô, thì ngày nay cần có các nguồn năng lượng thay thế.
Nhiên liệu hóa thạch là nguồn năng lượng phổ biến nhất hiện nay, nhưng nó không được coi là năng lượng sạch. Nhiều nguồn năng lượng thay thế khác phải được kết hợp nếu các thế hệ tiếp theo được mong đợi có năng lượng. Nước, gió, nhiệt bên trong Trái đất và mặt trời đều được sử dụng để tạo ra năng lượng. Năng lượng địa nhiệt và năng lượng mặt trời phổ biến hơn. Những ngôi nhà đang được sưởi ấm và làm mát, những chiếc ô tô đang được chạy, và điện được sử dụng tất cả từ những nguồn năng lượng thay thế khác nhau này. Tất cả đều là những ví dụ về năng lượng sạch, tốt hơn cho môi trường vì không gây ô nhiễm.
Đọc đoạn văn và quyết định xem những nhận định này là Đúng hay Sai.
